|
Chlorophyll
|
photosynthetic
accessory pigments |
|
|
Cell walls made of
|
cellulose
|
|
|
Store sugars as
|
starch
|
|
|
Cell division involves
|
cell plate
derived from the golgi apparatus |
|
|
Gametangia
|
reproductive organ
that houses & protects gametes |
|
|
unique features
|
Plants are adapted to life
on land |
|
|
Roots
|
root-like structures –
anchor and get water and nutrients; all land plants |
|
|
Waxy cuticle
|
limits water
loss; all land plants |
|
|
Stomata
|
gas exchange
and limit water loss; all land plants |
|
|
Vascular tissue
|
transport
water and minerals in the plant; vascular plants |
|
|
Stems with lignin
|
increases rigidity, thereby
increasing sun exposure; vascular plants |
|
|
Pollen
|
male gametes that
disperse without water; gymnosperms & angiosperm |
|
|
Seeds
|
protect & feed the
plant embryo; gymnosperms |
|
|
LEAF
|
performs
photosynthesis |
|
|
CUTICLE
|
reduces water
loss |
|
|
STOMATA
|
allow gas exchange
|
|
|
STEM
|
supports plant
(and may perform photosynthesis) |
|
|
WHOLE ALGA
|
performs
photosynthesis; absorbs water, CO2, and minerals from the water |
|
|
ROOTS
|
anchor plant;
absorb water and minerals from the soil (aided by mycorrhizal fungi) |
|
|
HOLDFAST
|
anchors the alga
|
|
|
The haploid
gametophyte produces |
eggs and
sperm by mitosis |
|
|
sporophyte
|
The eggs and
sperm unite, and the zygote develops into the diploid |
|
|
bryophytes
|
One lineage gave rise
|
|
|
Have flagellated
sperm |
require
water (e.g., rain) for fertilization |
|
|
Liverworts
|
grow in moist,
shaded areas. |
|
|
Mosses,
|
showing the
stalks that carry spore-bearing capsules. |
|
|
Bryophytes include
|
mosses
|
|
|
Mosses have a dominant
|
gametophyte
|
|
|
Most of a mat of moss consists of gametophytes
|
These produce eggs and flagellated (swimming) sperm
– The zygote grows out of gametophyte into sporophyte |
|
|
Leafy-green gametophyte
|
haploid generation
– Which produces sperm & eggs by mitosis |
|
|
Ferns and seed plants
|
were derived from
early vascular plants and contain – Vascular tissue – xylem & phloem – Well-developed roots – Rigid cell walls & stems – Flagellated (swimming) sperm |
